E6430 with sleep issues and 5GHz wireless issues

I just finished installing Yosemite 10.10.3 on my E6430 and everything is working great except for two issues.

My specs

E6430 Core i5 NVS5200/HD4000 Optimus disabled in bios

8GB RAM

WiFi card is AzureWave Broadcom BCM94352HMB

I followed this guide to get the WiFi and bluetooth working 

http://www.tonycrapx86.com/network/104850-guide-airport-pcie-half-mini-v2-89.html

I'm using the latest chameleon boot loader 

 

My two issues are as follows:

1.  I can't recover from sleep - I have to hard reboot if it goes to sleep.

2.  I can only see 2.4 GHz wifi networks.  I cannot see any 5GHz networks.  I have tried the kexts on the above site to no avail.

 

Any help would be appreciated.

1) Sleep doesn't work with the Nvidia card - no solution so far. Use Caffeine.app to keep system from sleeping or you'll have to hard reboot

2) You need the new patch for 10.10.3 here .

run this from the terminal and reboot.

sudo perl -pi -e 's|\x41\x83\xFC\xFF\x74\x2C\x48|\x66\xC7\x06\x55\x53\xEB\2B|g' -i.bak /System/Library/Extensions/IO80211Family.kext/Contents/PlugIns/AirPortBrcm4360.kext/Contents/MacOS/AirPortBrcm4360

sudo touch /S*/L*/E*
sudo kextcache -Boot -U /

Jake, I think we are getting somewhere but we are not quite there.  I installed the fakeSMC and now I have the following in the system info:

Card Type: AirPort Extreme  (0x14E4, 0x2123)

  Firmware Version: Broadcom BCM43xx 1.0 (7.15.166.24.3)
  MAC Address: 00:6b:9e:06:13:ed
  Locale: Unknown
  Country Code: XT
  Supported PHY Modes: 802.11 a/b/g/n/ac
  Supported Channels: 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14
  Wake On Wireless: Supported
  AirDrop: Supported
  Status: Not Associated
 
Still no higher channels and the country Code I think needs to be US.

Still the same.  

Also as far as the sleep thing.  Is there a way to use the HD4000 only and still be able to use the HDMI out for an external monitor?  I tried using the skipNvidiagfx and turning on and off optimus but could not find one that would allow it.  If I do that will sleep work?

Sleep will work with HD4000 (Optimus Enabled), but not HDMI as it's tied to the Nvidia card. Wern has gotten sleep to work on the E6420 with NVS4200M, perhaps he could assist with how it gotten it to work.
